2025 biology talkshow: 我可能忘了你?漫談失智症

from 雷比特生物空中講 · host 雷比特老師

以電影《王牌冤家》為引,深入探討記憶的神經生物學機制與失憶症(Amnesia)的科學研究進展。詳細介紹神經科學史上著名的 H.M. 病例,解釋了海馬迴在形成新記憶(順行性失憶)中的關鍵作用,並區分敘述性記憶和程序性記憶的儲存位置。也闡明長時程增強作用 (LTP) 作為記憶「寫入」的分子基礎,並破除關於腦震盪導致失憶的常見迷思。最後,介紹 2025 年最新的研究突破,如使用 CRISPR-dCas9 移除老化大鼠腦中的 DNA 甲基化標籤,以及利用光遺傳學技術「喚醒」腦震盪小鼠中被沉默的記憶,表明記憶可能並未消失,只是「無法讀取」。 聽完後可以自主進行線上測驗,檢視學習成效喔~(需要登入gemini) 測驗網址  https://gemini.google.com/share/92fb7e693fab Powered by Firstory Hosting
